Ten reasons to buy an ENDOTHERMIC by
TERMOMECCANICA GL
The "EUROTEK ENDOTHERMIC” spray-drying booth, by TERMOMECCANICA GL, due to the
whole new technologies implied in its working process, is a whole innovative booth.
Doubtlessly the presentation of the system will not be exhaustive of the variety and complexity of the
thermal-physical aspects that are the basis of its operation, but we felt the need to write a short handbook
highlighting this wonderful product.
We tried to sum everything in the motto "10 reasons to choose Endothermic by TERMOMECCANICA GL“
and presented you 10 questions and 10 answers explaining why the technological innovation, efficiency of
operation and savings shape this one as the spray booth of the future.
1: Why does the Endothermic represent a real breakthrough in the world of painting booths?
The Endothermic spraybooth does not need any burner nor any sort of thermal power plant. Those parts
become unnecessary since there is no need of heating all of the air that gets inside the booth: the surface to
bake is heated by convention by means of the radiant panels positioned on the booth walls.
The various processing stages and removal necessary airflow is ensured to the system by a single outdoor
unit named „Central Air Treatment (CTA) “.
Inside the CTA are placed both one in-take and one out-take turbo ventilators and two 11Kw motors. Each
motor is, obviously, coupled to its turbo ventilator, so the CTA is a self-standing and independent unit,
making it possible to save much space thanks to its vertical development instead of the widespread building
way.
2: Even if there is nor the burner neither any appropriate heating section, how is the heat diffused
inside the spray booth?
The heat is diffused through the radiant panels fixed on the walls; the shape to be formed is heated by
radiation. The panels are made with a high technology material: with low energy absorption we achieve a
diffused radiation result.
3: Depending on the heating lamps experience, is the power consumption equally high?
No, it is not. Thanks to this innovative technology, the booth power consumption, during painting and / or
drying phases, is lower than 60Kw.
The installed power includes the simultaneous operation of engines, lights and radiating panels during all of
the processing stages. The absorption, however, is considerably lower than the installed capacity thanks to
the irradiation control system that cyclically turns the panels on and off.
4: Is it possible to control the temperature both on the source of irradiation and on the work piece?
At any time the operating temperature is under control both on the panel (in the surface transmitting the
heat) by means of appropriate probes inserted inside it, and on the template, thanks to a special provided
gun.
5: May be a source of risk to have heartened panels on the walls during the painting phase?
There is no danger in the temperature lead to the panels during the painting phase, always assuming that the
necessary conditions of heat exchange are kept, because the panels will while they work it is never exceeded
the temperature of 140 °. Nevertheless we know that the paint becomes dangerous when in contact with a
400 ° and above heat surface, just like it happens with the common lamps working at temperatures well
above the indicated threshold.
6: During the painting phase is it necessary to use special operating cares on panels?
Thanks to the unique TERMOMECCANICA GL technologies and materials, the temperature of the panels
at the maximum operating temperature is expected to be compatible with the common use electrostatic
protective aprons and any overspray on the walls may be cleaned with an ordinary solvent soaked cloth,
when the panel is cold and the paint has gone dry.
7: What happens, for example in the winter months, when then cold outer air gets inside the booth
through the CTA system?
In this conventional operation case, the system works by heating the air and the heat is transmitted to the
shape in the cab thanks to the convention effect.
So the outside temperature is very important to achieve the temperatures necessary to perform the various
processing stages. In the Endothermic spray booth, the heat is transmitted with a radiation process, so the todry piece is heated directly by the heat-waves. In addition, three are the reasons why the air that is
introduced into the booth does not cause any change in the process:
1: the temperature rise due to the compression that the air undergoes to when pushed by the fan towards the
interior of the booth;
2: 0.3 m/s air speed, used only during the painting phase, is not perceptible by humans;
the convention heat transmission is an inefficient system and therefore has a low cooling capacity too.
8: How is the air flow inside the Endothermic booth during the different process phases?
This is the only existing system where you can manage, as independent variables, the various processing
stages, the heat transmission (which is necessary to perform coating and drying) and the air flow rate (which
is necessary for over-spray abatement and solvent-emissions removal). Moreover, the adoption of a stand-by
device allows, thanks to the inverters varying the number of revolutions of the fan motors, to adjust the
airflow rate to the best rates during every single working phase to reduce the power absorption.
During the drying phase more saving is provided by to the need of performing just a motor (CTA) cycle of
one minute every ten operating minutes.
9: If compared to a traditional system, does this body shop spray booth offer real money savings?
This question allows us to articulate the answer in 3 key points:
A) Reduction of the processing time: if an average masking, coating, drying and cooling cycle takes about
120 minutes, with the Endothermic spray booth we are able to reduce the total processing time of about
15/20 minutes. It is important to focus on the fact that the time reduction is obtained not only during the
drying stage, but during the phases when the operator works inside the booth. The drying time reduction
results in lower labour costs and higher daily production.
B) Savings in working costs: The operational cost saving is the key evolution step enabled by
TERMOMECCANICA GL Endothermic spray booth.
C) Building cost savings: since there is no need of a generator, you will avoid undergoing any administrative
and supervisory survey, saving lots of money and time, as well as needing a smaller CTA unit for the booth
to work properly.
It is important to emphasize you will not need any thermal power station, without any connected loss of
money and time.
10: As a final analysis, what is the environmental impact of the booth?
If compared to a traditional cabin, we do not release into the atmosphere any combustion gas and not require
any ductwork installation.

Cost differences between an usual and a TERMOMECCANICA GL
Endothermic spraybooths:
Example of the cost differences between an usual and a TERMOMECCANICA GL Endothermic
spray booth:
Booth with a standard 240000 Kcal/h burner, with an hour diesel consumption of 24 Kg x €1.70 diesel =
€40,80 per working hour.
The cost is lowered by 30% to €28.50 since the burner switches off whenever it reaches the operative
temperature.
Max consumption of the panels/hour 45,00kW/h
kW/h price:0.20€
Medium consumption of the panels/hour 35 kW/h
TOTAL: ........................................35 kW of medium electrical power consumption/hour x €0.20=7.00€/hour
SO:
Diesel-based operative hourly cost:....................28.50 €
Radiating panels-based operative hourly cost:.....7.00 €
SAVING: ......................................................... 21.50 €
